Is there a way to compute this sort of thing for other antenna/feedline
combinations ?
For example, I have a 43 foot monopole with 63 radials, using 45 feet
of LMR-400 coax transmission line. Is there a simple formula or
relationship for this sort of thing ? Is it just a question of
feedline length to antenna wavelength or something that counts. (I am
presuming, without knowing, that the considerations for a 40 dipole
might be different from a 43 ground plane antenna.)
Happy Trails.
